Vitamin B12 and Folate
Vitamin B12 and folate (vitamin B9) are essential nutrients that work together to support energy metabolism, brain function, DNA synthesis, and the production of healthy red blood cells. Deficiencies can lead to fatigue, brain fog, anemia, and in some cases, neurological symptoms. This test helps assess your levels and supports dietary and supplementation decisions.
